FASTENING DEVICE.

Original application filed May 28, 1920, Serial No. 384,809. Divided andthis application filed October. 23,

To all whom it may concern:

Be it known that I, JACOB F. LANGENAU, a citizen of the United States,and a resident of Cleveland, ounty ofCuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Fastening Devices, of which thefollowing is a specification, the principle of the invention beingherein explained, and the best mode in wh ch I have contemplatedapplying that principle, so as to distinguish it from other inventions.

The present improvements, relating, as indicated, to fastening devices,have more particular regard to looks or hasps of the sort used ontrunks, suit cases and the like, characterized by having a hasp in theform of a link that is carried by a pivotal member so as to engage. witha hook-likemember or projection when in looking position. The object ofthe present invention is to provide supplemental means for securing suchpivota1 member in place when the hasp is in such locking position, themeans ordinarily provided for this purpose consisting. of a pin or astud member which more or less tightly fits into an aperture in the baseplate to which said member is attached. 7

To the accomplishment of the foregoing and related ends, the invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims, the annexed drawing and thefollowing-description illustrating but several of the vari ousmechanical forms in which the principle of the invention may beembodied.

In said annexed drawing Fig. l is a front elevation or plan view of afastening device embodying my present improvements, said device beingshown in its closed or looking position; Fig. 2 is a side elevation ofsaid device with parts shown in section as indicated by the line 22,Fig. 1; Fig. 3 is a view similar to Fig. 1, but showing the pivotalhasp-carrying member removed so as to disclose more clearly thesupplemental locking device; and Fig. 4 is a transverse section of suchsupplemental fastening device, the'plane of the section being indicatedby line 4-4, in Figs. 1 and 2. v

Referring to the general assembly views as my improved device shown inFigs. 1 and 2, the familiar parts of the fastener comprise two baseplates 1 and 2, which are Serial No. 596,182.

to the latter in turn is a projection 4, preferably in. the form of ahollow boss, to the outer edge of which is pivotally attached by meansof a pin 5, a hollow member 6 having swingably secured thereto a link 7,

which constitutes the aforesaid hasp. The

free end of this link, in other words, is adapted, when member 6 isswung outwardly, to engage beneath the hook-like projection 3 on late 1.and when saidmember is thereupon pressed backwardly against the plate 2,the two plates, with the parts of the trunk or equivalent article willbe forcibly drawn together.

As shown in Fig. 2, the pivotal axis 5 of the member 6 should liewithout the plane of the link in the locking position of the parts justdescribed so as to minimize any tendency on the part of member 6 toswing outwardly to releasing position; however, I have found itdesirable to add a supplemental locking device in order to secureagginst any but purposeful opening of the loo 1.

With this in view, the upper end 8 of the member 6, which is curved topresent a convenient finger. piece for operation of the look, as bestillustrated in Fig. 2, is provided with-a necked stud 20 fixedly securedthereto, such stud, in a locking position of the parts, being arrangedto project through an aperture 21 in plate 2. The portion of said plate,in which aperture 21 is thus formed, is preferably raised to provide aflat boss, and in the recess thus provided on the rear or under-face ofthe plate, a recurved spring 22 is housed, the arms of such springnormally intersecting the aperture and being adapted to grip the sidesof the stud 20 in the fashion best shown in Fig. 4. The action, in otherwords, is somewhat similar to that of a snap fastener in that the headof the stud 20 is rounded so that upon being forced into opening 21, itwill spread the two arms of spring 22 apart and the latter then willengage with the reduced portion or neck of said stud and thus hold thelatter against accidental dislodgment from such aperture 21. Spring 22is convenlently held in place by means of a cover plate 23 that closesthe depressionv formed by the boss in which such aperture .21 is formed,suchplate and the spring beingsecured to the under-face of the part 2 bymeans of a1 rivet 24k, as clearly shown in Figs. 2 and 3.

The foregoing supplemental locking de vice, it will accordingly be seen,aiiordsa 'sinrle and *et effective a 'encv for retaining-the member 6with the hasp 7 "in locking position. There is, of course, noparticular-strain placed upon the stud 20, so-

is=to bercgarde'd as a division or continuation of such co-pending case.

@ther modes of-applying the principle-of my invention maybe employedinstead=of the one explained, ch-ange'being made as regards-themechanism herein disclosed, provided the means stated by anyof thefollow ing claims Orthe-equivalent ofsuch stated means'be employed. I

I therefore particularly point out tinctly claim as my invention 1. Infastening device of the character described, the combination with twoplates designed to be secured in abutting relation OIl'tlle parts tobefastened together, a hookand dislike projection rigidly mounted on oneof said plates, a member pivotally attached to the other plate, and alink carriedbysaid member and'adapted to engagesaid projectiozr to "locksaidplates togethen said mem her being provided with a necked studadjacent its free end; of a resilient member secured on-thecorresponding plate adapted to engage such stud antl'thus to retain saidmember against accidental movement.
